HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 357,793, dated February 15, 1887.

` Application tiled April i9, i856. Serial No. 190,301. (No model.)

To all whom, iz? may concern.-

Beit known that I, JOHN GEORGE SMITH, of the city of Montreal, in the District of Montreal and Province of Quebec, Canada, mechanical engineer, have invented certain new and useful Improvements in Heating Apparatus; and I do hereby declare that theibilowing is afull, clear, and exact description of the same.

My invention has reference to the special means used to heat public or private buildings, and is equally applicable to steam or hot-wa ter systems.

In place of the box-coils, pipe-circulations, or chambers connected together by hollow standards, I propose to substitute a cluster of vertical sections so constructed and secured together that each section shall have a sepa- Arate and positive circulation of it own, the

whole combined forming a radiator, the inlet and outlet being at the same end of said radiator.

My invention consists in a radiator formed of independent sections, each having` proper vertical passages for steam, with inlet and outlet passages which communicate with all the sections. In connection with thcseit also includes an air-pipe, which extends through the sections and communicates with each, and

is provided with an air-valve which permits the escape of air from all the sections, and certain details of construction which are fully hereinafter described..

For full comprehension of my invention reference must be had to the annexed drawings, in which- Figures 1 and 2 show vertical transverse sections through one section of the radiator, and Fig. 3 a side view partially broken away.

Similar letters of reference indicate like parts.

A is a section, composed in this case of legs A', A2, and A3, the first of these being nearest to the inlet and the last to the outlet.

a, ci and a a are the faced joints.

B B are apertures formed in the base corresponding eXactly in size and position to each section.

Through the openings B B passes the inletpipe G, connected with any desired source of supply, whether of steam or hot water, and

communicating with the inlet-leg A of each section through small apertures c on its top side. The outletpipe D, communicating with the several sections through the apertures d on its side, is taken through theopenings B B and out of the saine end of the radiator as the inlet.

B2 B2 are openings near the top of each section, through which passes the pipe E, for taking off the air, c ebeing openings into it, and E the air'cock at en'd of the pipe.

G is a diaphragm extending downward from the top side of chamber near leg A', and reaching, as in Fig. 2, into a recess or pocket, H, constructed in the bottom of. the ('hamber, thus forming a trap or water seal. The same objectviz., a water seal-may be attained` as shown in Fig. l, by the substitution for the eXtra length of the diaphragm G and the recess H of a secondary diaphragm, G', projecting upward from the bottom plate. By the construction of these diaphragms, and with or without the pipes C D, the dow and return are practically separated, so that the sectional radiator above described and shown can be used for steam as well as hot water, and this particular feature may be utilized in radiators of differing construction.

I prefer to place between the faced joints A A and A A of the sections rubber or other washers, H H', fitting tightly on the pipes C, D, and E.

The operation of theinvention will be easily understood from the foregoing and the accompanying drawings. 'Ihe hot water or steam passes through the holes c in the inletpipe C into the leg A of each section, and thence, as shown by the arrows, till through' the holes d d it entersl the outlet-pipe D and passes off. By this means a positive separate and individual circulation is set up in each section, and this will be the case even if the pipes C and D are omitted and the inflow of steam or hot water be through the openings B corresponding closely to leach other, and the outlet through the holes B', the faced joints a a and c at beingtitted closely together.

Having thus described my invention, I beg to state that what I claim is as follows: i

l. A radiator formed of independent sections, each having circulating passages, inlet and outlet pipes C D at the bottom, and a Ventpipe, E, at the top, all passing through and communicating with the sections and securing them together7 substantially as described..
